Not sure why CONFIG_EFI_LOADER is always selected for ARM.

What about doing this?

diff --git a/lib/efi_loader/Kconfig b/lib/efi_loader/Kconfig
index d2b6327..a2ea9c0 100644

 config EFI_LOADER
        bool "Support running EFI Applications in U-Boot"
-       depends on (ARM || X86) && OF_LIBFDT
+       depends on X86 && OF_LIBFDT
        default y
        help
          Select this option if you want to run EFI applications (like grub2)
